GENERALIZED AGE-ADJUSTED EFFECTIVE MODULUS METHOD FOR CREEP IN COMPOSITE BEAM STRUCTURES. PART 1 - THEORY

The age-adjusted effective modulus method for approximate analysis of structures exhibiting linear aging creep law and underlying Bazant's theorem is generalized to a form which is more accurate for composite beam structures in flexure. A rigorous derivation of a linear algebraic relationship between the internal force histories and the deformation histories of the beam is given using the integral operator symbolics. (Author/TRRL)
